How do we end up fooling ourselves? Well, our knowledge of the world around us is far from perfect, in fact, it is very partial. Physicists know this well.

Our senses by which we perceive the world are limited. We see poorly at night, we can only focus our eyesight on a narrow field of view right in front of us, the edges of our vision remain blurred. We can only hear certain frequencies. There is only a certain amount of the light spectrum we see. Our smell is vastly inferior to that of a dog.
